Expander, Control Panel, and Keypad Setup
Before installing the Expander and wireless point transmitters, it is recommended that the Expander, control panel, and a hard-
wired keypad be temporarily wired together. Panel programming should then be performed and each transmitter assigned a
point code. (It is easier to complete the necessary programming if all the equipment is in the same location.) The procedure is
as follows:
1. Make sure power has been removed from the control panel.
2. Using a short piece of multi-conductor cable, temporarily connect a hard-wired keypad to the control panel. (Refer to
Radionics keypad and control panel installation instructions.)
3. Remove the Expander’s cover. Use a small flat-bladed screwdriver to gently pry housing cover open at pry point slots
indicated. (See Figu re1.)
4. Using another short piece of multi-conductor cable, temporarily connect the Expander to the control panel by connecting
DATA, AUX+ and AUX- terminals. (See Figu re3.)

5. Set up the Expander to respond to MonoBus address 7 or 8 by moving its address jumper.
(See Figure 4.)

6. Apply power to the control panel.
7. Follow the Radionics control panel operating instructions and installation instructions to set up communication between
the keypad, control panel, and Expander. Note that when setting the Supervision Interval in the RF Parameters Group of
the panel’s program entry guide, a "1" indicates a 4-hour interval, not a 24-hour interval. (A "0" selection, however, still
means a 12-hour interval.) Make sure the Expander address set-up at the control panel matches the Expander address
jumper selection. If everything is working properly, the REPLY LED on the Expander should be flashing. (See Fi gure2.)
8. Follow the control panel operating instructions to assign point codes to each transmitter. Assign point codes to Command
transmitters using the same procedure described for RF keypads
